PROCESS FOR THE PREPARATION OF A DECORATED SUBSTRATE

摘要

A process for the preparation of a decorated substrate comprising the steps of: submitting the substrate to a treatment to prepare its surface for the application of a coating; applying a coating to the surface of the substrate in one or more cycles; covering the surface of the substrate with a sheet comprising a decoration which is to be transferred to the surface of the substrate; and heating the substrate and the sheet comprising the decoration to effect the transfer of the decoration from the sheet onto the substrate. In this process, the coating is cured using electromagnetic radiation having a wavelength shorter than 400 nm, until a coating is obtained having a Tg between 50 and 130° C. and a scar resistance at 200° C. of at least 3N and wherein the temperature during the transfer of the decoration to the substrate is from 180 to 220° C. The process is particularly suited to the decoration of heat sensitive substrates, like MDF or wood.
